DESCRIPTION AND OPERATION

Glass, Frames and Mechanisms

Vehicles may be fitted with front power operated

windows (rear windows manually operated) or both

front and rear power operated windows.

Front only Power Windows
The switches located on the front door trims are used

to raise/lower the front windows. Depress and hold

the up/down switch locations to raise and lower the

window.

Front and Rear Power Windows
The five switches, located on the front driver door

trim, control the four windows. Switches are also

provided on the other three door trims for operation of

that window only. The child lock switch on the front

driver door can be used to disable the rear switches.

Auto down - the driver’s window switch can be

pressed and held for approximately 1 second to

automatically fully lower the driver’s window.
All electric windows operate with the ignition switch in

the ‘ON’ or ‘accessory’ positions. When the key is

returned to the ‘OFF’ position, power window

operation is available for one hour (or 45 seconds if a

door is opened).

DIAGNOSIS AND TESTING

2.  Connect voltmeter or test light between lower

circuit breaker terminal and ground to ensure

electrical supply at this point.

Before making any of the following trouble checks,

make sure that the battery is fully charged, and turn

3.  Check operation of accessory relay in relay block

by turning the ignition switch on and off and

observe the relay operation by sound or feel. If

All Power Windows are inoperative

does not move, the glass coupling or gear teeth

have failed.

5.  If the motor does not run, disconnect the wires at

the motor in order to check for voltage attach feed

wire while actuating the window switch. If there is

no voltage at the motorfeed terminals, check for

voltage at the switch feed wire. If there is voltage

at the switch, replace the switch.

Window inoperative in one direction

6.  Check the operation with the individual and

master switches. If only one switch is inoperative,

replace the faulty switch.

7.  If the window will not function correctly from either

switch, check for defective wiring between the

switch and the motor. If the wiring leads are open,

replace the wiring.

8.  If the window operates normally in one direction,

the motor is not defective.

Power window operates sluggishly

9.  Check the regulator and window runs for binding.

Adjust the runs, repair and lubricate the regulator.

Lubricate the runs with silicone lubricant.

10. Check for frayed insulation where the window

wires may partially ground. Check for loose

connections which will cause high resistance.

11. Check motor current draw during operation (place

an ammeter in series with the ground lead of the

battery). Motor current draw should not exceed 12

amps during normal operation and should exceed

20 amps at stall. If the current is above 12 amps

during operations of the window, readjust the

glass mechanism. If the stall current is below 20

amperes at stall, look for poor electrical

connections.

12. Motor current draw when disconnected from the

regulator plate should not exceed 5 amps.
